To all whom it may concern.-

Be it known that I, PAoLo VIGANO, cottonweaver, a subject of theKing'ofItaly, and a resident of Triuggio, Lombardy, in the Kingdom of Italy,have invented certain new and useful Improvements in and Relating toShuttle-Box-Operating Mechanism for Looms, (for which I have obtainedpatents in Italy, dated November 15, 1891, No. 30,769; in France, datedFebruary 9, 1892, No. 219,259; in Belgium, dated February 10, 1892, No.98,302; in Great Britain, dated February 13, 1892, No. 2,851; inSwitzerland, dated February 10, 1892, No. 4,883; in Austria-Hungary,dated March 14, 1892, [No 35,651, Austria; No. 68,618,I-Iungary,] andinGermany, No. 70,288, dated February 13, 1892,) of which the following isa specification, reference being had to the accompanying drawings.

My invention relates to looms which have several shuttles with theirboxes adapted to move vertically and in which the change is effected bya jacquard mechanism substantially in the manner hereinafter described,and definitely pointed out in the claims following the description.

In the accompanying drawings, Figure 1 is a side elevationof part of aloom-frame provided with my improved shuttle-changing mechanism. Figs. 2to 5 show in diagram the different positions of the rockinglever, towhich is attached the rod carrying the shuttle-box.

Figs. 6 to 9 show the arrangement of the holes in thejacquard-cardscorresponding to the different shuttles which are to beset in action. Fig. 10 is a'broken side elevation to a larger scale thanthat in Fig. 1, showing the parts having direct relation with thechanging mechanism. Fig. 11 is a broken end view of the partsrepresented in Fig. 10. Fig. 12 is a section on the line to y, Fig. 10.Fig. 13 is a detail view illustrating the slotted connection between thelever c and the bell-crank lever e.

In the drawings the improved mechanism is supposed to be applied to aloom provided with four shuttles.

Referring to Figs. 1, 10, and 11, the numeral 1 indicates a pedestal orbracket (shown by dotted lines) mounted on the loom-frame. In

said pedestal or bracket is journaleda shaft ally connected to a rod 9",to be hereinafter described. On the upper end of the rod r is fixed across-head 5, to which is pivotally attached the upper end of a hook s,which is adapted to engage the teeth 4." and impart to the cylinder 71 astep-by-step rotary movement.

The alternating upward movement of the hook s, causing the rotation ofthe cylinder '6 upon its axis,is effected by the eccentric-rod L, whichis j ournaled on an eccentric L, mounted on a rotating shaft L", asclearly shown in Fig. 1, by which the lever m is made to oscillate uponthe fixed center 0 and to impart, through the medium of the link 19, anoscillating movement to the bell-crank lever g, which turns upon thefulcrum h and communicates a reciprocating movement to the rod 7',connected with the aforesaid hook 8 through the medium of theintermediate connecting mechanism, hereinafter described.

An important feature of my mechanism relates to the action of the twobell-crank levers d cl 6 e, which are both adapted to turn upon the samepivot H, fixed upon the lower portion of the loom-frame. These leversaccomplish the change of the shuttles in one or the other direction,according as they are with their longer arms at one or the otherextremity of two slots 15 M, Fig. 2, parallel to the plane of Fig. 1,these slots being formed in the plate .2 and situated in the verticalplanes of oscillation of the two levers d d and e 6, respectively. Theplate z is fixed upon the frame of the loom by means of descending arms,2, and the length of the slots a depends upon the amount of thevertical displacement of the shuttle-boxes. Above each of these slotsare secured to the plate 2, by means of spring-bolts, bow-piecesprovided with notches f g at their extremities. With these notchesengage the upper ends of the longest arms of the levers d d e 6 whenthese reach the right-hand or left-hand extremity of their movement.

The rocking lever c, fixed at c to the rod B, which acts upon theshuttle-box A, provided with four compartments in order to cause it tomove upward or downward, is attached at c and at 0', respectively, byslotted connections to the extremities of the shortest arms of thelevers (l d and e 6, adapted to oscillate upon the pivot H. As thelevers 61 (Z and e e do not stop in an intermediate position, but passwith the upper extremity of their longest arms directly from theposition f to the position 9, or vice versa, the lever 0 may occupyalternately one of the four positions represented in Figs. 2 to 5, thesepositions being as follows:

First. The two upper extremities of both of the levers d (l e e are onthe left-hand side, Fig. 2that is to say, at f, Fig. 1. Then the twoshortest arms of the same levers are in the same line. The leverd isbelow and the lever 6 above. The point e" is also below and the rod B isat the lower extremity of its movement and presents the first shuttle tothe action of the shuttle-driver.

Second. The upper extremity of the lever d d is on the left-hand side,Fig. 3that is to say, at f, Fig. 1-and that of the levere e on theright-hand side at g, Fig. 1. The rocking lever c is in a horizontalposition 0 c c', Fig. 3, and the rod 13 presents the second shuttle tothe action of the shuttle-driver.

Third. The positions of the levers d d e e areinverted, Fig. 4. Theupper extremity of the lever e eis on the left-hand side at f,Fig. 1,and that of the lever d d on the right side atg, Fig. 1. The rockinglever cis still placed horizontally and the rod B presents the thirdshuttle to the action of the shuttle-driver.

Fourth. In the fourth position, Fig. 5, the two levers d d e e have boththeir upper extremities on the right-hand sidenamely, at g, Fig. 1. Theshortest arm of the lever 01 cl is turned upward. The shortest arm ofthe lever e e is turned downward, and these two arms are in the sameline which coincides with the direction of the rocking lever c, theextremity c of which is in the highest position, so that the rod Bpresents the fourth shuttle to the shuttle-driver.

It remains to set forth the manner in which the levers d d e e areoperated by the chain of cards actuated by the cylinder 2'. At half thelength of the longest arms of the two levers d d e e are pivoted the twobars 6 u,whieh by reason of their weight tend to bear upon a pin at thelower extremity of the lever m. The bars are provided with two noses. Bymeans of the nose below a projection on the lower end of the lever m asit oscillates from the left to the right hand side tends to push thelongest arms of the levers d d e c to the right-hand extremity of theslots in the plate 2. The lower extremity of the lever (1 whenoscillating in the opposite direction to that of the lower end of thelever m acts upon the upper nose of the two bars 25 and it and tends topush the longest arms of the levers d d e c to the left-hand extremityof the slots in the plate .2.

Two rods 5, Figs. 10, 11, and 12, take part in the alternating upwardmovement of the mechanism for actuating the hook s and carry weights 0at their lower extremities. The rods 8', bent above, bear upon the cardsof the pattern, which are moved by the cylinder 1'. If the card inaction has two holes, the rods 3' with their counterweights U do notencounter any obstacle whatever and descend, bearing upon theheel-pieces i u of the shortest arms of the two bars t u, raising theirlongest arms and causing the upper noses of these bars to engage withthe terminal point of the lever g, which has the defect of displacingthe longest arms of the two levers d d e e to the left-hand extremity ofthe slots t u in the plate z and consequently setting the first shuttlein action, Fig. 2. If, on the other hand, the card presents only onehole, there is only a single rod .9, which descends, and a single barwhose longest arm is raised and pushed in the above-described manner.According as the hole is on the right or on the left hand side the leverd d or the lever e 6 will be displaced. The arrangement of the holes inthe cards is represented in Figs. 6 to 9.

The card shown in Fig. (3 corresponds to the position of the levers d de e in Fig. 5 and to the setting in action of the fourth shuttle.

The card shown in Fig. 7 corresponds to the position of the levers (Z (Zc e in Fig. 4 and the setting in action of the third shuttle.

The card shown in Fig. 8 corresponds to the position of the levers d (Zc c in Fig. 8 and the setting in action of the second shuttle.

Lastly, the card shown in Fig. 9 corresponds to the position of thelevers d d e e in Fig. 2 and the setting in action of the first shuttle.

If two shoots of the same color are to be introduced, the sameshuttle-box has to operate, in which case it is sufficient to let twocards with the same arrangement of holes follow each other.

What I claim is- 1. In a loom, the combination of verticallymovableshuttle-boxes, a jacquard mechanism, a rod carrying the shuttle-boxes, arocking lever for raising and lowering said rod, two pivoted bell cranklevers attached at their shorter extremities to said rocking lever, bars75 and u pivoted intermediate their ends to the longer arms of saidbell-crank levers, mechanism for engaging said bars to rock thebell-crank levers in one direction, mechanism for engaging said bars torock the bell-crank levers in the opposite direction, and two weightedrods arranged over the extremities of the said bars and controlled bythe jacquard mechanism, said rods when dropped by the jacquard mechanismengaging the extremities of the bars 6 and u and throwing the latter outof engagement with one of the operating mechanisms and into engagementwith the other, substantially as described and for the purposespecified.

2. In a loom, the combination of verticallymovable shuttle-boxes, ajacquard mechanism, a rod carrying the shuttle-boxes, a rocking leverfor raising and lowering said rod, two bell-crank levers pivoted upon acommon center and pivotally attached at their shorter extremities tosaid rocking lever, bars t and u pivotally attached intermediate theirends to the longer arms of said bell-crank levers and provided withprojecting hooks or noses, mechanism for engaging said hooks to rock thebell-crank levers in one direction, an oscillating lever (1 adapted toengage the hooks to rock the bell-crank levers in the oppositedirection, and two weighted rods arranged over the free ends of thebell-crank levers and controlled by the jacquard mechanism and operatingwhen dropped by said mechanism to oscillate the bars t and u, and throwthe hooks into the path of the oscillating lever q, whereby thebell-crank levers are thrown in the opposite direction, substantially asdescribed and for the purpose specified.

In witness whereof I have hereunto set my hand this 26th day ofDecember, 1892.
